The current forecast has Hurricane Ignacio passing northeast of the Big Island on Monday and north of Maui on Tuesday. Ignacio was 585 miles (940 kilometers) east-southeast of Hilo, Hawaii, with top winds of 140 miles per hour, making it a Category 4 hurricane on the five-step Saffir-Simpson scale, the center said in an advisory at 11 a.m. Forecasters at the Central Pacific Hurricane Center said conditions are right for it to continue strengthening Saturday, but upper-level winds will weaken the storm in the following days. It is expected to pass north of Hawaii in the coming week, but forecasters warn that there is still uncertainty about the storm’s path. “If Ignacio shifts to the right, we could see light winds, more humid conditions, and localized heavy rain. Everyone should continue to monitor the progress of Ignacio during the next several days,” the National Weather Service told The Honolulu Star-Advertiser.
